Low-oxygen fluorocarbon as an agent for ophthalmology

A process for preparing an oxygen-physiologically acceptable fluorocarbon mixture having a dissolved oxygen content of less than 6% by volume, wherein the fluorocarbon is selected from the class of saturated, perfluorinated hydrocarbons in which all of the hydrogen atoms are replaced by fluorinated atoms, or partially fluorinated alkanes having the general formula RFRH or RFRHRF that can be present in a liquid or gel-like state, wherein RF is a perfluorinated alkyl group and RH is an alkyl group;

• and wherein the fluorocarbon is deoxygenated using a heterogeneous oxygen getter, and stored in an oxygen-lacking state until use.

• wherein said fluorocarbon is deoxygenated using a heterogeneous oxygen getter;
• and proportionately mixed with an oxygen-containing fluorocarbon to obtain a desired oxygen concentration within a range of 0% to 6% by volume;
• and stored in an oxygen-lacking state until use.

Use of a physiologically acceptable fluorocarbon having a dissolved oxygen content of less than 6% by volume as an agent for ophthalmology, wherein the fluorocarbon is selected from the class of saturated, perfluorinated hydrocarbons in which all of the hydrogen atoms are replaced by fluorinated atoms, or partially fluorinated alkanes having the general formula RFRH or RFRHRF that can be present in a liquid or gel-like state, and wherein RF is a perfluorinated alkyl group and RH is an alkyl group.
